摘要： 采用固相反应法和湿化学法制备LiNixMn2-xO4正极材料, 分析了合成反应机理. X射线衍射表明, 采用固相反应法合成前驱物时, 得到的是Ni1Mn2O4+Mn2O3混合物而不是成分分布均匀的固溶相Ni3/4Mn1/4Mn2O4, 因此最终容易生成贫镍的尖晶石结构LiNixMn2-xO4(0

Abstract: The synthesis reaction mechanisms were analyzed for the cathode materials LiNixMn2-xO4, which were synthesized by the solid-state reaction method and the wet-chemical method, respectively. XRD data indicated that a mixture precursor of Ni1Mn2O4 and Mn2O3 would be preferred for a solid solution of Ni3/4Mn1/4Mn2O4 when the solid-state reaction method was used for the material synthesis. As a result, the last product would be the mixture of NiO, LixNi1-xO and spinel LiNixMn2-xO4 (0
